Demand/Resuscitator Valve

The LSP Demand/Resuscitator Valve is designed to provide 100% oxygen to a breathing or non-breathing patient in an emergency situation. The valve is designed for use with a mask, endotracheal tube, or tracheotomy tube.

The Demand Resuscitation Valve complies with AHA guidelines recommending that 100% oxygen be given to victims of a heart attack and/or smoke inhalation. The valve can be used in conjunction with a portable oxygen cylinder equipped with a pressure regulator or with a central oxygen source. The valve operates on a regulated oxygen supply of 40-60 psig (275 to 413 kPa) and reduces this pressure to a physiologically acceptable level with a pressure limit of 60±5 cm H2O. This prevents excessive buildup of intrapulmonary pressures and over-inflation of the lungs.

The slight negative pressure created by a spontaneously breathing patient’s inspiratory effort triggers the valve from a non-flow state to a flowing state. The greater the inspiratory effort, the higher the flow. When the inspiratory effort stops, the flow stops. The non-breathing valve permits it to be used as a resuscitator in combination with a manually operated button located on top of the valve.

The Demand/Resuscitator Valve provides an accurate constant flow rate of 40 lpm to help prevent gastric inflation, as recommended by the AHA. It is also available with a minimum flow rate setting of 160 lpm.

Maximum cylinder use

Flow rate of 40 lpm is maintained at cylinder pressures between 200-2200 psig (1378 to 15158 kPa), allowing for complete use of cylinder contents

Easy to clean and service

Valve obstruction may be removed during resuscitation with minimal interruption, and may also be chemically disinfected

Durable, compact and lightweight

Will withstand corrosive materials and harsh weather conditions.

40 lpm Flow Rate (restricted flow)

As required in demand mode, 0-40 lpm at 50 psig (344 kPa);
in resuscitation mode, a constant flow of 40 lpm at 50 psig (344 kPa)

160 lpm Flow Rate

As required in demand mode, 0-160 lpm at 40 psig (275 kPa);
in resuscitation mode, a constant flow of 160 lpm at 40 psig (275 kPa)
